Illegal class name "" in class file

stepheneb · March 17, 2010, 8:51pm

We recently upgraded to JRuby 1.4. We are now getting an exception when
compiling a ruby class:

could not compile: because of: "Illegal class name “” in class file "

the Ruby file looks something like this:

require ‘java’

java_import “com.mycompany.DisplayType”

class Labeler

def initialize
@a = getDisplayType(“A”)
end

def getDisplayType(id)
DisplayTypes.find(id).label
end
end

I have been unable to find any help for this anywhere on the internet.
Any
suggestions would be greatly appreciated.

Interesting…the script you provided seems to compile and run ok on
JRuby 1.5 dev and 1.4.0 for me, so it’s nothing obviously wrong with
that script or the compiler’s handling of it…

Can you give JRuby 1.5dev a try, from http://ci.jruby.org/snapshots ?

The error looks like the compiler is generating a Java .class at
runtime that has an invalid class constant.

You could also try to specify the JVM property jruby.compile.dump=true
and we can pick out the appropriate bits from that log (which should
immediately precede the error).

First, let me clarify something I left out of the first post. The ruby
class
runs fine. The only way I know there is an error is the stack trace. I
recieve the same error with 1.5.

With jruby.compile.dump=true:

Thank you for your response. The original stack trace from the first
email
is the output when I set jruby.jit.logging.verbose=true. It doesn’t seem
to
show any script or method names. And the exception happens when I try to
get
the object as a java class, not when I am calling any of the methods.

stepheneb · March 18, 2010, 6:24pm

Ahh you know what, I read your original email wrong. Yes, it works
fine…what’s happening here is that something causes the compiled
Ruby script to be an invalid Java class (probably a compiler bug) and
so it just leaves it interpreted. There’s nothing functionally wrong
with that…it will continue to work, albeit a little bit slower.

So the logging I actually need from you is to set this property, which
will show failed methods and scripts. The one that fails around the
same time as that error is our culprit, and you can toss it into a
bug:

jruby.jit.logging.verbose=true

Ah-ha! It’s a bug in Spring!

On line 90, they do a parse with an empty string for the script name.
This is incorrect, and we should probably have an error for it. This
is also super inefficient…they’re re-parsing and in your case
re-compiling the incoming script for every call.

Note that this doesn’t appear to be their current source (for v3,
which now supports JRuby 1.4+), but this was the repository I found on
Springsource’s site.

You must also be specifying jruby.compile.mode=force, yes? Is there a
reason for that? Or perhaps Spring is doing it?

I am using the current release v3, which is also when we updated to
JRuby
1.4 and when we noticed the error. I am not setting the
jruby.compile.mode
so spring must be setting it to force. I will put something in the

Hi Stephen,

after serveral problems while running a ruby script via jruby with
spring (3.0.5.RELEASE) support i reached somehow the point where you
left off.
